The supervisor's phone list at 11pm
Several of your cleaners work alone in empty office buildings in the evening. A few engineers do solo callouts at night. Your procedure says someone checks on them. In practice, the evening supervisor rings each one at some point during the shift, between their own work, from a list on their phone.
Sometimes a call goes unanswered because the cleaner is vacuuming with headphones on. The supervisor tries again later, gets through, and moves on. Sometimes they forget one person entirely. Nothing records who was checked and when. If something went wrong, you would struggle to show what your procedure actually looked like on the night.
Why ringing round is fragile
Phone-based checking relies on one person's memory and attention for the whole shift. It does not scale: as more people work alone, the list gets longer and the gaps between calls grow. It is also reactive. A missed call is treated as normal, because it usually is, which is exactly the problem.
There is no defined point at which a missed check becomes a concern, and no defined next step. Should the supervisor ring again in five minutes, ring the site, send someone, call the emergency services? Without clear rules, people hesitate, and the hesitation is where the risk sits.
Employers generally have a duty to assess and manage the risks of lone working. How you do that is for your own risk assessment. The weak point we see is not the assessment but the day-to-day follow-through.
What informal checking costs
| Weakness | Consequence |
|---|---|
| Missed checks | A worker in difficulty is not noticed promptly |
| No escalation rule | People hesitate about what to do next |
| No record | Cannot show how the procedure was followed |
| Supervisor load | Checking crowds out their other work |
| Worker confidence | Staff feel less safe working alone |
The record matters for more than audits. After any incident, the first questions are when the person was last heard from and what was done when they went quiet. With ring-round checking, the honest answer is often a guess.
Supervisors carry the weight of it too. Being the only safety net for a dozen people across a night shift, with nothing but a phone list, is a stressful job that most of them never signed up for.
How we automate check-ins
- Check-in schedules tied to the rota, so each lone shift has expected check-in times based on your procedure, for example on arrival, at intervals and on leaving.
- Prompts on the worker's phone at each check-in time, answered with a single tap, or by text reply for basic phones.
- A missed check-in triggers a second prompt, then an alert to the supervisor with the worker's location, site details and contact numbers.
- An escalation path you define: who is contacted next, after how long, and what information they receive. The system follows it step by step and records each step.
- A discreet alert option on the worker's phone for when they need help, which starts the escalation immediately.
- A log of every check-in, missed check and escalation per shift, available to managers and for review.
Location is only used during working shifts and for safety purposes, and staff are told clearly what is recorded and why. We design that with you and, where you have one, your HR adviser.
A shift with automated checks
Cleaners and engineers tap to check in when prompted. The supervisor sees a board of everyone working alone, with their status, and only gets involved when something is missed. If a worker does not respond, the escalation starts on its own and the next person knows what to do.
The next day, managers can see that the procedure ran as intended, and any shifts where it did not. Staff know that if they do not check in, someone will notice.
Does this describe your team?
- Staff regularly work alone in empty buildings or on night callouts
- Checks are done by a supervisor ringing people
- There is no written rule for what happens when a check is missed
- Nothing records who was checked and when
- Your lone worker procedure depends on one person remembering
